Physical appearance of baking powder
Physical Properties:
The picture above is a household item called "baking powder". It is an odourless, white, powdery substance. Sodium bicarbonate has a melting point of about 50 degrees celsius (Sodium Bicarbonate, 2006). When baking powder is mixed with water, it produces sodium ions and bicarbonate ions. When acids are present in the mixture, they produce carbon dioxide gas (Romanowski, 2006). If baking powder was mixed with cold water, the mixture would be affected very little. When the cold water and the baking powder was mixed together, there were only little bubbles that were produced. This means that carbon dioxide was present during the reaction.
If hot water is mixed in with baking powder, it would have a major affect to the mixture. This is because the heat from the water made the baking powder react more than the cold water. Since there were a lot of bubbles foaming, there was a lot of carbon dioxide produced.The reaction between the hot water and the baking powder was very strong compared to the cold water and baking powder mixed together (Sodium Bicarbonate, 2006).
Chemical Properties:
Baking powder is well known to be used in baked goods as a leavening agent. A leavening agent is a substance that causes dough or batter to rise. This happens because when sodium bicarbonate is dissolved or heated in water, it produces carbon dioxide gas (CO2).This item is also known as sodium bicarbonate or sodium hydrogen carbonate . The chemical formula for baking powder is NaHCO3. This chemical compound is made up of 1 sodium atom, 1 hydrogen atom, 1 carbon atom, and 3 oxygen atoms (Sodium Bicarbonate, 2006).
The sodium atom is made up of 11 electrons, 11 protons, and 12 neutrons with a number of 3 energy levels. The hydrogen atom is made up of one proton, one electron, and no neutrons with only 1 energy level. The carbon atom is made up of 6 electrons, 6 protons, and 6 neutrons with a number of 2 energy levels. Each oxygen atom in the chemical formula is made up of 8 protons, 8 electrons, and 8 neutrons with a number of 2 energy levels (Bentor, n.d.).
